all whom it may concern: Be it known that I, EDGAR T. MEAKIN, reing inBerkeley. county of i-UamedieState California, have invented certain newd useful 1mprovemcnts in Nmrskidding Devices, whereof the following is aspeoification.

My invention relates to means for pro iting skidding of automobilewheels and s at its principal. object the prevention skidding bydelivering sand beneath the sole of automobiles. second object of myinvention is to so l or the sand beneath the wheels of the tomobile thatthe same will be effective in in windy Weather. A final object of myinvention resides in he particular arrangement and combination. i partshereinafter dcscril'ied. ,In the accompanying drawings Figure l is aplan view of an automobile which has been fitted with my invention, thebody of the antol'nobile having been re moved. .25 Fig. 2 is aperspective view of the auto mobile as shown in Fig. 1. v

. Fig. 3 is a plan View on an enlarged scale ,of a portion of Fig. 1.

"Fig. l is a detail view taken on an irregular section line and at aplane at right angles 159 Fig. 3.

*Figs. 5, 6 and 7 are detail sectional views showing two modified formsof-sand box with connections to the blast pipe. ;I ,.-,Fi 8 and 9 areside and plan views respectlvely of a modified arrangement, and Fig. 10,is an enlarged-detail of the imporin; parts of Fig. 8, parts beingbroken ewe .-'{T rouglhout the separate figures the same part is]esignated character. 'Reierring more particularlvto the drawji ,1designates the chassis of; an' automohiring the front wheels such as 2and i'engine of the automobile, the haust' pipe lffor which is shown at5, the exhaust ,nor-

Now at 7 I provide a T connection in the exhaust pipe from which I leadoff a bypass 8, the pipe 8 passing beneath the sand box 9 and thereafterdividing into the two branches 8S which I show as ru'nning rearwardlyand downwardly so as to discharge beneath the driving wheels 3.

The exhaust gases coming from the engine are normally prevented fromentering the bypass 8 by a valve 10 which is nor- 0 mnlly held over themouth of the pipe 8 as 7 clearly shown in Fig. 3, but which may beturned to the position indicated in dotted lines in Fig. 3, the latterposition the-- valve 10' serving to divert the exhaust gases 65 into thepipe .8 and to out off-the further passage of gases to the muflier.The-valve 10 has alevcr 11fix:ed.thereto,thewalve-and lever beingpivoted at the point 12 and I provide a link 13 which is connected withthe level-'11 at one end and at the other end with an arm 14 fixed onthe shaft 15. The shaft 15 may be turned in one direction to move thevalve 10 by means of a foot pedal 16 carried by an arm' 17 fixed to theshaft 15, previously mentioned. The shaft is,

however, normally held in such position that the valve closes theby-p:1ss 8 as previously mentioned and for this purpose I provide aspring 18 fixed at one end to an E0 arm 19, the arm 1 9 being fixed tothe shaft, while the other end of the spring 18 is secured to the fixed1nd or bar 20 rigid with the chassis. i I v Now the sand-box 9 isprovided with an inclined bottom which slopes (down on all sides to anopening 21 at the extreme lower end of "said box. Theoutlet 21 isnormally closed by a horizontal valve 22' mounted to turn about avertical pivot 23, and having rigid therewith an' arm 24:. The arm24 isconnected by alink 25 to a, lever or arm 26 and the shaft 15, previouslymentioned, so

i that the valve 22 is opened each time the by-' pass valve 10 isalsoopened. As shown In the preferred form in Figs. 3 and,4, the valve22ismounted within a. small delive chain: ber 27 the mouth 2 of which isinc ined in the direction of flow of the exhaust uses.

through the by-pass 8 in order to faci itate ,1 01.

the slipping oil" of the sand particles by the stream of exhaust gases.The pipe 8, more over, is enlarged somewhat immediately beneath themouth 28 as indicated at 29, the

pipe 8 projecting into enlargement 29 as shown at 30, so as to give anaspirating effect.

Instead of thearrangement shown in Fig. 4 I may dispense with the valveand accompanying features and allow the sand to enter the pipe 8directly shown in Figs. 5, 6 and 7. In .Fi 5 and 6 the lower end of thesand box -9 extends into an enlargement 29 in the pipe 8, the opening 28in the bottom of the box 9 being close to the bottom of the enlargement29 so that a small pile of sand always stands below the opening 28.However there is always a passage for the exhaust gases at each side ofthe pile of sand so that the gases may carry the sand away. [11 Fig. 7the sand. box 9{ is set at one side of the pipe 8 and connected theretoby a short upwardly inlinrd, neck ill. the ml at the mouth of the neat:being to the gases in the pipe 8.

Referring more particularly to Figs. 8, 9 and 10, 16 is a foot operatedlever connected by a link with pivoted arm 33 at the top of said arm.From be lower end of arm extends it link 34 valiicl'i runs back in thedirection of the link and connects with an arm 35 which adapted to turnthe valve .10" so as to open the mouth of. the bypass 8, at the sametime partly closing the pipe 5 and forcing into the pipe 8 in a mannersimilar to the action of the valve 10, the valve 10 l'mvverer liftingfrom the bottom of the pipe 5 The pip: 8 branches into the parts in themodified form as in the first mentioned form, but in the modified formthe mud guards .Y carry sand-boxes -10, the lower ends oi which areclosed by valves 22, a rib 39 closing a portion of the lower end of thebox 40. A link 36 con nects also with the lower end of the arm 33 andoperates the valve 22 by means of a pivoted'arm =l1.shown in Fig. 9 sothat the engine for driving the same, an exhaust pipe ower end of eachsand box 40 is opened at the same time that the valve 10 is raised.

Sand. from each box 40 drops into a noz" z-le 38 which ineloses the endof the pipe 8' and which is placed close: to the drive wheel as todeliver the sand thereto.

Having thus described my invention, I claim i- 1. The combination with avehicle, a gas for said engine, a bypass leading from said exhaust pipe,a sand- 3b,; adapted to deliver into-said by-pass, sai(l',b:v-pass beingadapted to deliver sand from said box beneath the Wheels, and a valve,iio nally closing said by pflSS to prevent passage of gasestherethrough, said valve progressively obstructing the exhaust pipe asit opens the by-pass.
